Overview

The LG 3390W1G014A is a genuine OEM 12-inch glass turntable tray designed as a direct replacement for a wide range of LG microwave ovens. When a microwave turntable cracks, chips, or breaks, uneven heating quickly becomes a problem since the rotating tray is essential for distributing microwave energy evenly across your food. This replacement tray restores full functionality with a part manufactured to LG's original specifications, ensuring a precise fit on the turntable coupler and roller ring inside your microwave cavity.

The tray is compatible with numerous LG models including the LMV2053 series, LMV1925 series, LMVM1935 series, MV1943 series, and many more. Because LG uses this same turntable dimension across a broad lineup, it serves as a convenient single-part solution for multiple appliance generations. Installation is simple — just place the glass tray onto the existing roller ring and coupler — with no tools required. As with any glass microwave component, handle with care during unpacking and cleaning to avoid breakage.
